Deceptively small, the Potterton Promax SL Heat is a powerful, high efficiency heat only boiler available in four outputs - 12kW, 15kW, 18kW and 24kW. All boilers are fully modulating and are small enough to be installed in standard kitchen cupboards. Unlike most other heat only boilers on the market, the Potterton Promax SL Heat does not need a pump overrun, making it easy and quick to install, with minimum disruption for the householder as no carpets or floorboards need to be lifted. Flueing options up to 20 metres mean that siting this powerful little boiler is very flexible and it has an efficiency rating of 'A'.
